I'm using a netbsd-3 boot loader to boot -current kernels. This worked
until recently. A kernel as of today panics when booting:

boot device: <unknown>
root on md0auvm_fault(0xc361a0c0, 0, 0, 1) -> 0xe
fatal page fault in supervisor mode
trap type 6 code 0 eip c01e52bf cs c01e0008 eflags 10282 cr2 10 ilevel 0
panic: trap
syncing disks... done
rebooting...

It panics with both  config netbsd root on ? type ?  and config netbsd
root on md0a type ffs.

Is this related to the boot loader? I'm hesitant to upgrade it since
recovering from a possible non-booting CF card is time consuming.

Thanks
